Hi all. Can anyone explain me a thing about using RequestDispatcher ? If cookies are disable and i use encodeURL to be sure to include "jsessionid" into url, is it correct that using "RequestDispatcher.forward" the url is not changed, so it does not include jsessionid (this happen to me with tomcat 3.2.1, when my servlet call a jsp to expose results) ? Right way is to use "sendRedirect" (this mean a roundtrip to the web browser) ? it's not very....good... Other way ? Thanks in advance. Max
